I have had some stomach problems (gastritis) in the past and so am fairly careful with what I eat and avoid foods I know can trigger a reaction.
I eat porridge most days and have realised that before I've even finished the bowl I have a mild stomach ache. This has probably happened for a long time but I've ignored it.
I get the same ache when I drink tea but I had put it down to caffeine and removed it from my diet.
Now I'm wondering if I actually have an intolerance to milk.
I had childhood eczema, and suffer with asthma so it's possible I have an issue with dairy.
Would symptoms come on so quickly if it's an intolerance?
